As a part of a research programme on GPS network otmitisation, the problem of redundancy was studied experimentally with a view to minimizing the cost/benefit ratio. A number of networks which had been surveyed for scientific purposes and thus provided operational guarantees of high quality - long measurements times, three-dimensional benchmarks with autocentring, sites selected to avoid multipath effects and completely open above 10°, etc. - werw analysed. Using the single baseline approach, and starting from the highest possible redundancy, baselines were gradually eliminated to reach the minimum pattern with r=n-1 vectors measured. The results suggest that the best cost/benefit ratio is obtained when redundancy is of the order of 2. Our experimental results show good agreement with those obtained from simulation.

Abstract
As a part of a research programme on GPS network otmitisation, the problem of redundancy was studied experimentally with a view to minimizing the cost/benefit ratio. A number of networks which had been surveyed for scientific purposes and thus provided operational guarantees of high quality - long measurements times, three-dimensional benchmarks with autocentring, sites selected to avoid multipath effects and completely open above 10°, etc. - werw analysed. Using the single baseline approach, and starting from the highest possible redundancy, baselines were gradually eliminated to reach the minimum pattern with r=n-1 vectors measured. The results suggest that the best cost/benefit ratio is obtained when redundancy is of the order of 2. Our experimental results show good agreement with those obtained from simulation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
